现有研究强调了数据资源的重要作用,但缺乏探讨如何整合数据资源以赋能产品创新绩效。遵循“条件-行为-结果”的分析思路,研究基于信任视角,探究组织间计算型(理性)与关系型(感性)信任如何通过稳定调整型、开拓创造型两种数据资源整合行为赋能产品创新绩效。利用华南地区两时点调查的222家制造企业问卷数据,研究采用PLS-SEM工具进行实证检验,得出以下结论:(1)计算型信任分别能够通过稳定调整型、开拓创造型两种数据资源整合行为赋能产品创新绩效;(2)关系型信任通过稳定调整型、开拓创造型两种数据资源整合行为与产品创新绩效存在非线性中介作用关系,即适度的关系型信任能够分别通过两种数据资源整合行为提升产品创新绩效,但是过高的关系型信任则无法通过两种数据资源整合行为提升产品创新绩效;(3)稳定调整(“拿来主义”)与开拓创造(“二次创新”)两种数据资源整合行为对于产品创新绩效的影响存在交互效应,当企业通过计算型、关系型信任同时提高两种数据资源整合时,能够更好地赋能产品创新绩效。研究回应了制造企业如何进行数据资源整合发挥数据要素价值的重要问题,能够为充分发挥数据作用赋能企业高质量发展提供重要启示。

Recently, charge or spin nonlinear transport with nontrivial topological properties in crystal materials has attracted much attention. In this paper, we perform a comprehensive symmetry analysis for all 122 magnetic point groups(MPGs) and provide a useful dictionary for charge and spin nonlinear transport from the Berry curvature dipole, Berry connection polarizability and Drude term with nontrivial topological *** results are obtained by conducting a full symmetry investigation of the matrix representations of six nonlinear response tensors. We further identify every MPG that can accommodate two or three of the nonlinear tensors. The present work gives a solid theoretical basis for an overall understanding of the second-order nonlinear responses in realistic materials.

【目的】研究塔罗科血橙新系、血橙8号和血橙9号3个血橙品种矿质营养元素周年动态变化及其相关性,掌握其养分吸收规律,为血橙科学施肥提供理论依据。【方法】以全年不同月份采集的3个血橙品种叶片为材料,测定叶片中干物质率、全N、全P、全K、Ca、Mg、全B、Fe、Cu、Zn、Mn含量,于果实成熟期测定果实各营养元素含量,分析叶片、果实营养元素含量的吸收规律及其相关性。【结果】叶片中,干物质率整体表现为血橙8号>血橙9号>塔罗科血橙新系;全B、Fe、Cu含量变化规律相似,血橙9号Fe含量达到最大值(78.30 mg/kg)的时间较其余2个品种早60 d;全K含量变化与全B、Cu相反,表现为成熟期和幼果期低、果实膨大转色期高;3个品种的全N、全P、Ca、Mg、Zn、Mn变化规律则有差异。果实中,血橙8号的干物质率、全N、全P、全K、Ca、Mg、全B、Cu和Mn含量最高,血橙9号为最低。相关性分析显示,叶片的全N含量与Ca、全B、Cu含量呈极显著相关(P0.05);果实的干物质率与全P、全K、Ca、Mg、B、Cu、Mn含量均呈极显著正相关;Zn含量与干物质率、全P、全K、Cu、Ca、Mg、全B、Mn含量呈极显著负相关;叶片全K、Fe、Zn、Mn含量与果实全P、全K、Ca、Mg、全B、Cu、Mn含量均呈显著或极显著负相关。【结论】果实发育前期(花期至幼果期),应以施用N、P、K复合肥及Ca、B、Fe、Mn肥为主;果实发育后期(膨大期至成熟期),注意补充P、K肥和Ca、Mg、Cu、Zn等微肥,平衡N肥的施用。

独乐寺观音阁内十一面观音像保存至今,泥胎存在裂隙、空鼓、脱落等病害。利用超景深三维显微镜、X射线衍射分析(XRD)、激光粒度分布仪等对观音像泥胎进行了材质分析。通过控制砂、纤维含量,分析泥塑试样的收缩性,并探索纤维含量对泥胎收缩性的影响规律。结果表明:观音像泥胎的制作原料取自当地,其中土颗粒粒径多在5~70μm之间,约占总量的79.5%;主要矿物成分为石英和伊利石,还有部分钠长石和钾长石,以及少量的高岭石。粗泥层含砂量约为35%,麦草(麦秆及麦壳混合物)含量约6%~9%,长度大多在2 cm以下;细泥层含砂量约为30%,麻丝含量约2.1%,长度大多集中在2 cm。麦草和麻丝的加入对泥胎的收缩均能起到抑制作用。随着麦草含量的增加,抑制作用呈现先增大后减小的趋势,掺和6%的麦草抑制作用最好;添加麻丝可使试样的最终线缩率显著减小,但麻丝的多少对线缩率的减小幅度影响不大。观音像泥胎的原纤维配比就有很好的抑制收缩效果。本次研究获得了十一面观音像泥胎的材料组成信息,得出了纤维占比对泥胎收缩性的影响,为十一面观音像的修复与保护提供了参考。
